UNITED STATES PATENT OEEIoE JOSEPH GRIMES, OF NORTH GROVE, INDIANA.

IMPROVEMENT IN BURGLAR-ALARMS.

ASpecification forming part of Letters Patent No. 152,104, dated June16, 1874; application tiled April 25. 1874.

. To all whom vit may-concern:

part of this specification, and to the letters` and figures of referencemarked thereon.

Figure 1 of the drawing is a representation ot' a sectional view ot' myburglar-alarm case,

and Fig. 2 is a plan view of the same'. Fig.

is a vertical transverse sectional view ot' Fig. 1.

This invention has relation to an improve ment on the store-counters forwhich l made application for Letters Patent on the 23d day of April,1874; and it consists in certain novel mechanism combined with saidcounters, and constructed in such manner that after they are movedtogether any attempt to separate them will cause an alarm to be sounded,thereby protecting from thieves any valuables which may be inclosed inthe counters, as will be hereinafter explained.

In the annexed drawings, A designates the front counter, and B the backcounter, both of which are mounted on caster-wheels a, so that in caseof tire the two counters can be readily rolled out of the store. Thefront counter A is provided with two horizontal bars, C O,which areguided by staples b, fixed into the rear edges of two partitions, A A',and these bars are connected together by means of a bar, I), secured onone end of a rod, D. This rod D extends forward and through the frontot' the counter, and has a l1and-crank,d, on its front end. Inside ot'the counter a ratchet-Wheel, d', is keyed on rod D', with which a pawl,e, engages. This pawl e can be released from its ratchet-wheel by meansof a key. Each bar O is provided with hooks ff, which can be made toenter eyes g g on the front edges ot' partitions B B in the back counterB, and thus secure the two coun- When they are thus secured, the pawl ewill engage with the ratchet-wheel d.' on the actuating-rod D', and lookthe parts securely in position. In the space between the two partitionsB B in the back counter B I arrange a train of wheels,which are actuatedby a spring, and provided with al hammer for striking` a bell, E. Thiswheel-Work, l

`freely through a vertical staple, K, rising from the bottom of thecounter B, which staple serves as a fulcrum for the latch when thelatter is moved laterally. The notched portion of the latch lies in arack, R,whieh is secured to the lower bar O when the counters aretogether, and so engages with this rack that any attempt to move thecounters apart will slide the stand H from beneath the escapement-armh., and allow theV alarm to be sounded. Before moving the counterstogether, the post or stand H must be adjusted beneath the arm h, andthe alarm mechanism wound up. The latch J is then lifted, and held up bya verticallymovable hooked rod, I, which is passed down through the topofthe counter B. When the counters are brought together, and fastened bymeans of the hooks and eyes, as above described, the hooked rod I ismoved so as to allow the latch J to drop and engage with the teeth ofthe rack B.

It will be seen from the above description that a safe, or any objectinside ofthe counter, cannot be reached without giving an alarm. Inpractice, the counters may be lined with metal.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the two portable counters A and B, of suitableconstruction to hold and carry goods, as described, of a locking ldeviceand an alarm mechanism, operating together, for the purpose set forth.

y 2. The rack It on lower arm O, in combination with the lever J, stapleL, and removable block H, substantially as and for the purposes setforth.

In testimony that I claim 'the above I have hereunto subscribed my namein the presence of two witnesses.

JOSEPH GRIMES.
